Life History: To wait for females, males perch in forest clearings or edges on bare twigs about 3-12 feet above the ground; they will often patrol from these perches. Females lay eggs singly on young leaves and seedlings of the host plants. Caterpillars feed on leaves and rest in nests of rolled or tied leaves; fully-grown caterpillars hibernate.

Flight: One brood from April-June, emerging as early as late January in peninsular Florida.

Range: Nova Scotia and central New England west through southern Manitoba to the Dakotas and northeastern Wyoming; south through most of the eastern United States to Florida, the Gulf states, and Texas. White-fringed populations occur in west Texas, New Mexico, and central Arizona south to central Mexico.

Conservation: Not usually required.

NCGR: G5 - Demonstrably secure globally, though it may be quite rare in parts of its range, especially at the periphery.

Management Needs: None reported.
